Abstract: 1412735 Treating liquids UNITED KING- DOM ATOMIC ENERGY AUTHORITY 13 Sept 1972 [24 Sept 1971] 44759/71 Heading C1C [Also in Division F4] A process for the treatment of a suspension or colloidal solution (e.g. sewage sludge, protein suspension, slime) comprises forming the suspension or colloidal solution into discrete integral forms (e.g. drops), freezing the forms by contact with refrigerant, thawing the frozen forms and separating liquid from solids. The refrigerant may be a liquified gas (e.g. butane or fluorinated hydrocarbon) or kerosene. The forms may pass down or up a column during freezing and thawing. The freezing may be done by evaporating liquified gas or by liquid cooled by a heat exchanger (e.g. evaporator) in or outside the freezing zone. The thawing may be done by condensing gas or by liquid heated by a heat exchanger (e.g. condenser or hot water coils) in or outside the thawing zone. In Fig. 3 the apparatus comprises spray means 30, freezing zone 43, thawing zone 44 and separating zone 45, 46. The liquid in zone 43 is cooled by circulating it through evaporator 38 of a refrigeration system; the liquid in zone 44 is heated in the condenser 40 of the refrigeration system which also comprises compressor 41. In Fig. 4 (not shown) liquid from the freezing zone is cooled in a flash evaporator, the resultant cooled liquid is returned to the freezing zone and the resultant vapour is passed via a compressor to a condenser for heating liquid used in the thawing zone. In another embodiment (Fig. 5, not shown) liquid from the freezing and thawing zones is cooled and heated respectively by contact with an immiscible liquid which has been cooled and heated in a flash evaporator and condenser respectively. The different zones may be in separate vessels.

Abstract: 1,101,350. Fluidized reactors. DISTINGTON ENGINEERING CO. Ltd. 2 Nov., 1965 [4 Nov., 1964], No. 45030/64. Heading B1F. In a reactor in which a solid is fluidised by admitting a gaseous medium through a distribution plate 11, corrosive attack on a steel shell 12 in the event of the lining vessal 10 failing and gas leakage occuring is prevented by spacing the lining vessal 10 from the shell 12 and filling the space therebetween with the gaseous medium at a higher pressure than the pressure existing within the lining vessal 10, thus any leakage of gas resulting from failure of vessal 10 will be inwardly from space 13 to the interior of vessal 10. The space 13 is connected by a pipe 15 with the introduction chamber 14 for the gaseous reactant. A valve may be provided in the pipe, enabling any leakage to be determined. The differential pressure between the space and interior of vessal 10 may vary with the distance above the plate 11 if the fluid energy absorbed by the fluidised bed is high, in which case the space 13 is divided into compartments (Fig. 4, not shown) with valved pipes leading to each compartment to control the pressure in each compartment.

Title: Hydraulic device
IPC: A01B63/111
Filed: 1961-12-20
Abstract: 943,869. Tractor power-lift mechanisms. H. MOLLY. Dec. 20, 1961 [Dec. 27, 1960; Jan. 10, 1961], No. 45667/61. Heading A1P. An automatic draft, hydraulic control device for a tractor comprises a continuously acting pump supplying through conduit 1 a slide valve 4 which has a throttling portion 15 for the pressure fluid before passing it through a non-return valve 3 to a ram. A by-pass conduit 10 connects the pump to an outlet 9 and is controlled by a spring loaded valve 11 connected with pressure fluid on its reverse side by a conduit 13 which allows differing pressures to reach the valve for different positions of the slide valve 4 whereby a minimum amount of pressure fluid passes through the throttling point 15. In the position shown in Fig. 3 the ram is held in position. Movement of the slide valve to the right or left in consequence of variations in draft load operates or retracts the ram respectively. In the constructional embodiment shown in Fig. 6 the valve 11 is incorporated in the slide valve 4 and is shown in the open position in which the pressure fluid delivered through conduit 1 follows the arrows to the exhaust conduit 9. In this position the slide valve 4 holds the ram 14 against movement. When the slide valve is moved to the right, pressure fluid is fed through passage 13 to the reverse side of the valve 11 to close it whereby the fluid is then fed through the throttling point 15 and the non-return valve 3, which is also incorporated in the slide valve, to the ram 14. In the fully closed position of the valve 11 all the pressure fluid is diverted to the ram whereas in a partially closed position holes 41 in the valve 11 allow an escape of fluid to exhaust thus providing a slower lift. A stop 53 on the ram engages a rod 49 just before the valve reaches an end position and the other end of the rod is therefore moved to operate the slide valve to release pressure from the ram. A safety valve 44 is incorporated and has associated with it a balancing piston 57. From the safety valve pressure fluid is fed along conduit 43 to chamber 46 to operate the slide valve to allow the pressure fluid to exhaust. The holes 41 in the valve 11 are so arranged that fluid passing therethrough causes the valve to rotate. A device for controlling a double acting piston associated with rod 14 is also described.

Abstract: 949,117. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 10, 1962 [Dec. 20, 1961], No. 45723/61. Heading G6C. An apparatus for removing metal fission products from the coolant gas of a nuclear reactor comprises a filter bed of glass fibres or bodies which absorbs the fission products. The filter is intended for use with high temperature gas cooled reactors using nodular ceramic or cermet fuels, the fuel particles being contained in graphite. At the operating temperature of such a fuel element, 1600-1800‹C., fission gases such as krypton remain within the nodules; radio-active iodine diffuses from the nodules slowly enough in relation to its half life to ensure that none will reach the outer surface of the fuel. Fission product metals such as caesium, strontium and barium however have relatively long half lives and diffuse rapidly through the carbon to be picked up by the coolant gas. The filter is located downstream of the reactor, and upstream of the heat exchanger and will consequently be operating at 700-800‹C. A single filter may be provided, or a number of separate filters, each associated with a fuel channel or group of fuel channels. Preferred glasses are those based on the oxides of potassium, caesium, iron, aluminium, calcium and/or silicon. The filter is preferably thick enough to produce a coolant gas pressure drop approximately equal to that induced by the reactor. The filter shown in Fig. 1 comprises a mass of glass bodies 8 contained in a stainless steel tube 1. Silicon wool and gauze filter rings in the top and bottom of the tube separate the glass bodies 8 from the inlet and outlet ports. Pipes 17, 19 and valves 14, 15 enable the coolant gas circulation through the filter to be shut off and replaced by a filter decontaminating flow. Since the decontaminating flow is free of fission products, the gas will absorb the contamination from the filter surface. During operation of the reactor, heating coils 20 reduce the coolant temperature drop caused by its passage through the filter. The filters may be paired so that while one is functioning, the other is being decontaminated. A single filter may be used, housed within the pressure vessel immediately above the core, and of sufficient absorption capacity to outlast the reactor. The fuel element for which the filter system has been conceived comprises uranium carbide nodules coated with graphite disposed in a carbon or graphite matrix enclosed in a graphite fuel can.

A light source 1 produces a laser beam a which is interrupted by shutter 2, reflected by mirror 3, collimated by lenses 4, 5 and fed to a half mirror 6 which supplies two beams, one to mirror 8 and one to mirror 7. Mirror 7 reflects light to a rotating prism 9 arranged to reflect light and cause a beam to scan along one arm of an X-shaped opening in support surface 11. Mirror 8 reflects light to a rotating prism 10 causing a beam to scan along the other arm of the opening. Light reflected from a bar-coded label on the lower surface of an article on support surface 11 is focused by lenses 18, 19 and received by detector 20 and fed to a discriminator 21. The shutter 2 may be a rotating perforated disc (Fig. 4, not shown). Alternatively light from the source may be collimated and fed to a rotary mirror having alternating transmitting and reflecting segments allowing light to pass to mirror 8 or reflecting light to mirror 7 (Fig. 6, not shown). A rotary beam splitting mirror may be used to supply three beams to three rotating prisms (Figs. 7, 8, 9, not shown). An arrangement using four rotating prisms is described (Fig. 11, not shown). The support surface is arranged inclined in the direction of travel of the article so that the prisms and source can be arranged with horizontal axes (Fig. 15). The articles interrupt sensors 13, 16, 14, 17 which control the opening and closing of shutter 2 so that a scanning beam is not produced if the article is not in a sensing region.
